To tlllfwhomz'z Concern:

lie Ait known that l, llonnr B. Woon-` resident of lizittsliixrggh,y inthe connty of Allegheny and State of Pennsylvania, have invented certainnew and useful improvements in Tug ,'Vlheel-Rims, of whichy thefollowing is a specification.'

' `My invention relatesto the construction of wheel rims, and moreparticularly the construction of the tng'rims let the bullf wheels andband wheels well 'drilling rigs.v

Une object of this inventionl is to provide a tugrirn ot'novel'eonstrnetion which Vconiforming 4part of v.bines great strengthand rigdity'witli a.

minimnnrweight and which is easily constructed and readily assembled anddismembered in the application and use of the rim.

A still further object of the invention is the provision oi' a wheel rimharing the novel details ot' vonstruetion and the ai rangement ot' partsshown in the drawings, more fully described hereinafter, andpartirnlarly pointed ont in the appended claim.

Referringr now to the drawings, forming part oi' this si'ieeilieation,Figure l is a plan, partly in seetion, showingr the bull wheel of a welldrilling rig having a seetional tup;

l. In the accompanying drawings, the bull wheel and band wheel turims'embodying woirrrr, a citizen, of the United States, and

in Fig. .5, is made froiri a7. thin rolled Isteel l plate,l ofsubstantially unitorzn thickness, which is pressed or stampedbetweensuit able foi-ming guides so asto forni a transrersely fiat orstraight peripheral snrfane 2 and haring integral flanges 3, 3 attheedges 7 0 defining' the width of the tug rin1, the flanges ,25extending` inwardly, in substantial parallel planes. The rim l shownlisformed of four duplicate"sections or segments, (the number l oi sectionsbeing governed ordinarily by the,

diameter of the wheel rim) and eaclisee` d tion is curved I lengthwiseto' a predetermined radins inorder to form a rim of theilesired:"diarneter.` Two parallel encircling,r

` indentations are pressed` into the flat periphery :2 oi the rim'sections to form rope 2grooves 4 and 5 for the ball ropes used intransinittiinif power from the band wheel to the bull wheel oi a Welldrilling rig, and the grooves, 'which may be made semi-Cir- 85 enlar incross sertion. preferably are formed with flat inwardly converging sides6, 6 in the manner shown in Fig. 5. u

ln the hull wheel shown in Figs. l to l the ser-,tional tugr rim A isconnected by conrerg'ii'igr spokes T to one vend of the tubular bnll'wheel shaft l, this shaft having a. rnd- The 'gudgeons ave spiders S)whieh fit tightly into the ends of the shaft B and the spiders areprovided :it 9b 'one end with a peripheral flange 10 which engages withthe end of the bull wheel shaft to assistin locating and maintaining thegadgeons 8. 8in axial alinernent` with the shaft l.' (See Fig. 1..)Rivets 1l are used 4100 to sedare` the gndgeonsto the shaft, althoughany other approved fastening meansv may be employed.

Each `"section ot' the tugl rim A is provided with two oi the spokes 7,which are shown rigidly fastened at one end by gusset plates The innerends of the spokes 7, which may b9 convenientlymade of rolled steel.channel beams7 extend between the parallel faces of the annular legs ofthe two flanges 14, 14, the flanges 14 being riveted to the shaft B,

vand bolts 15 `beingemployed to detachably fasten the spokes 7 to theflanges 14. The abutting ends of the rim section are detachablyconnected by splice plates 16 on the marginal anges 3, 8 thereof, whichare fastened by rivets 17 to theflanges 3, 3 at one end of the rimsectionand which are secui'ed by bolts 18 to -tlie flanges 3, 3 at rimsections, the helpers which also eX- tend outwardly being riveted to theSpokes 7 of the tug rim. The helpers 20, 21, and `22 are positioned 'atsuccessively greater distances from the periphery of the rimiA,'.the

dog and helpers being employed to assist in shifting the bull ropes inremovingv and replacing these ropes onthe tug rim A of,

the bull wheel, as is frequently necessary in the operation of the bullWheel.

That portion of the bull Wheel shaft B adjacent to the tug wheel isemployed to store unused portions of the' well drilling cable and inorder to provide sufficient storage capacity, a spool Ci is adjustablysecured on the shaft, the spool being arranged to move toward and awayfrom the tug rinil A. As shown, the arms of this spool are formed ofrolled steel channels Q3 which are detachably connected to one anotherby suitable bolts 24 and which have a clamp .25

thereon by which the spool is frictionally held in adjusted position onthe shaft.

The spool side of the tug rini A is provided With a series of turningpins 28 which are conveniently formed in this case of a short piece ofwrought metal pipe and a bolt 29 which extends through the pipe andthrough suitable holes in the flanges 3 of the tug rim. The turning pins28 are employed to rotate the bull wheel manually in renioving andreplacing the bull ropelon the tug rim A i-n the usual and well knownmanner.

Secured on the turning pin side of the tug', wheel. is a series of cableprotectors 30 having inwardly -bent ends, these 'protectors being made.of flat bars and being riveted to one end of the Z-sliaped knees 31, theother end of the knees'being detachably fastened to the spokes 7 bybolts 32. The edges of the cable protectors 30 are rounded to preventcutting or fraying of the drillingl cable in Winding and univinding thecableon the shaft B, these protectors being provided on' alternatespokes 7 to prevent the drilling cable from fouling on the tug rimturning pins 28. L

1 it is supported in suitable bearings, the shaft rims to all metalwheels.

The bull wheel shaft B is also provided at one end with the usual brakewheel l), u which, as shown, is made in sections; and has a laminatedwooden brake riui formed of wooden cants QG which are fastened to ltheouter ends of spokes Q7, the spokes being dctachably secured to theshaft B in the same manner as the spokes of the tug rini The :brakewheel also has cable protectors 3l() which are fastened on the spoolside ofl the r bull Wheel in the `saine n'ianner as on the tu g i'iniand turning pins '29 which aril niadc of Wood,.are tightly driven inholes of suitable size in the gndgeon side of the brake wheel to providemeans for manually turning the bull Wheel froin the brake wheel cud ofthe bull Wheel shaft. The brake wheel D, not forming part ofthisinvention, its construction is not further desciibed.I

. In the band wheel construction shown in Figs. 6 and 7, the band wheelE is built up solidly of a series of boards or planks 35i so as to makea laminated wooden wheel. This Wheel is provided with a shaft 34 bywhich being keyed to the .i'netal hubs 35, 35 of which there'is one oneach side of the web Q theiwheel'E, and the hubs are fastened lilythrough bolts 3G to the web of the wheel itself is an' old and wellknown construction. Secured on one. side of the band wheel lil so as tobe concentric with the periphery of this wheel,v is a sectional nietaltug iiin A embodying the novel features of my invention. This tug rim isessentially the saine as has been described in eonnection'ivith Figs.y 1to 5. In the case ofthe band wheel E there are no spokes, however,connecting the rini to the shaft for the wheel, and a series of brackets37 and 38 are employed in fastening the tug rim A to the side of thewooden band wheel E. (See Figs. 6 and 7 l Similar brackets may be usedto fasten these As shown, the brackets 37 are formed of short pieces ofrolled steel channel bea-nis, one flange of the beams being providedwith holes through which the bolts 36 extend in fastening the rimsections to the band wheel, 115

the bolts 3G, of which there'are two for each bracket, also extendingthrough registering holes in the webof the band wheel E. A

l bracket 37 is provided on one end, and a sec- .ond bracket 38 at anintermediate point in 120 the length of each section of the tug riin A,

,these brackets being fastened by rivets to -the flanges 3 of the rimsections.

The brackets 37 at the ends of the riin sections have a short 4pieceofchannel beam 40 125 riveted thereto, the two pieces of channel beain37, 40 being placed back to back so that the flanges of the shorter`section will proieet outwardly and these outwardly pro- Vfootingflanges are provided with holes 130 This wooden band wheel constructionIn 9 which register with similnrholes in one end Dit the langes 3 of therim sections.

The bull Wheels and band Wheels equipped 'with my improiied tug rim willbe 'operated in itlieusuzil and wel] known manner.

The advantages of my .invention will be l oli 'ppnrent to those skilledin the art. My iinpl'oved pressed'steel tug rim provides a deineligibleriin which` easily and quickly erected :ind disinemlierefil and'trzinsporteiil 'from place to place.
